### reactants compared to products

if you start with a higher concentration of reactants, will the equilibrium concentration of the products be larger?

In the expression for k, the reactants are in the denominator. So when there is higher pressure of reactants, the equilibrium constant is actually smaller because you are dividing the pressure of the products by a larger number.

The equilibrium constant would be smaller with a higher concentration of reactants since the reactants make up the denominator of the formula.

Yes, the concentration of the products will be larger because the high amount of reactants will turn into product to satisfy equilibrium. K stays the same though.

### Re: reactants compared to products

Whether or not product equilibrium concentration will increase depends on the reaction's K constant.
For example, if you start with a higher concentration of reactants and products and the reaction's K value is very high, yes, product will be formed and the product concentration will be increased at equilibrium. But if the reaction's K constant is ridiculously low, it is actually possible that the product's concentration will go DOWN so that the product/reactant ratio satisfies the K constant.
